To aZZ'wtof/n it may concern:

it known that we, Lawnrion B. Jexcnns and drohen F. fir'i'cniies,citizens of the inited States, both residing at lllorcester, in thecounty lliorcester and State of Massachusetts. have `iointly inventedcertain new and useful niprovements in iVeft- Replenishing- Looms, ofwhich the following is a specification.

Our invention relates to automatic weft replenishing looms, andparticularly to that class of looms which have shifting or changeshuttle boxes at one end of theilay, and Ya magazine for fillingcarriers at the other end of the lay,.and filling detecting mechanism atthe magazine end of the lay, to detect practical or substantialexhaustion of filling in the active shuttle. i

The object of our invention is to improve upon the construction ofautomatic weft replenishing looms of the class referred to,

and more particularly to provide an improved mechanical fillingdetecting mechanisni, preferably located at the. back of the lay, andhaving a pivotally mounted filling detector located at the back of thestationary shuttle box at. the magazine end of the lay. and having itsfilling eiigaging end pass through an openingl in the back of theshuttle box, and an opening in the sluit-tlc, to engage with the fillingon the bobbin in the shuttle, .and through intermediate mechanism tocause the movement of a dagger carried on and moving with the lay, onthe practical or substantial exhaustion of tilling in the activeshuttle, to cause the filling carrier re leasing mechanism to be putinto operation.

in our present improvements one of the important features is theoperation of the dagger connected with the filling detector or fceler,which dagger puts into operation, on the substantial exhaustion offilling in the active shuttle, mechanism connected withk the weftreplenishing mechanism to supply fresh filling to take the place of Jrhesubstantially exhausted filling in the active shuttle.

ln our present improvements, the dagger referred to. is normally in itsoperative position, so that on the substantial exhaustion of filling inthe active. shuttle to a predetermined extent, the dagger does not haveto be moved into its operative position, but is in this position, andready on the forward movement of the lay to putv into operationmechanism connected with the weft replenl e t i l l l 1 l t i a n Fig. 3a section, on line o, o,

ishing mechanism. lf there is a sutlicient 4amount of filling on` thefilling carrier in the active shuttle, the engagementr of the filling fother mechanisms connected with the filling selecting mechanism` andtransferring mechanisni, and other mechanisms shown and describedinother applications for patents now pending in the Patent Office, and tobe hereinafter referred to.

Tire have only shown in the drawings a detached portion of the magazineend of a weft replenishingloom, with our improvements applied thereto,sufficient to enable those skilled in the art, to understand theconstruction and operation thereof.

Referring to the drawings :-Figure l is an end view of the magazine endof a weft replenishing loom of the class referred to, with ourimprovements applied thereto; the magazine, the stationary shuttle box,and the lay beam are shown in section. Fig. 2 shows, on an enlargedscale, the filling detecting mechanism at the back of the lay, lookingin the direction of arrow a, Fig. l.

n the accompanying drawings, 1 is a part of a loom side or end frame, 2a part of the loom arch, 3 the lay carried on the lay swords 4 which arepivot-ally mounted aty their lower ends at 5, and operated through aconnector to the crank shaft 7, in the usual way. On the lay 3 ismounted a stationary shuttle box 8, containing a shuttle 9 carrying abobbin 10 having filling 10 thereon. All of the above mentioned partsmay be of the usual and well known construction.

At the rear of the lay 3, back of the shuttle box 8, is in this instancesecured a stand 11, having an outwardly extending arm 11 carrying a stud12, on which in this instance is loosely mounted the hub 13 on the lowerend of an upright lever 13. Near the middle portion of the uprightlever13 is a boss 13, carrying a stud 14, which has loosely mounted thereon asecond upright lever 15. The upper part of the lever 15, and the upperpart of the lever 13 are odset to form a yokeshaped lever, having inthis instance the enlarged engaging ends 13 and 15, between whichextends in this instance the ballshaped end 16 on one arm of anangleshaped filling detector 16, which has a boss 16 pivotally mountedon a stud 17 on the stand 11.

A helically coiled contraction spring 15L is attached at one end to anextension 15 on the lever 15, and at its other end to a lug 13fLextending out from the lever 13. The spring 15a acts to hold theenlarged end 15 on the arm 15 in engagement with the head 16 on thelever 16. The other arm of the filling detector 16 enters through anopening 8 in the back of the shuttle box 8, and an opening 9 in the backof the shuttle 9, to engage the filling 10 on t-he bobbin 10, and detectpractical or substantial exhaustion of filling on the bobbin, in thesame manner as shown and described in my said application for LettersFatent, Serial No. 322,680.

The downwardly extending arm 15 of the lever 15 has its lower endpractically in horizontal alinement with the ulcrum of the hub 13 of thelever 13, see Figs. 2 and 3, and is connected through an adjustable rodor link 18 with an extension 19 on the hub 19 of a dagger 19. The hub 19of the dagger 19 is pivotally mounted on a stud 20, see Fig. 2, on thestand 11. rlhe upper part of the lever 13 is connected through a rod orconnector 21 with one arm of an angle lever 22 which has the hub 22loosely mounted on a stud 23 on the stand 11, see Fig. 2. rEhe other armof the angle lever 22 is pivotally connected with the upper end of avertically moving rod 24.

The lower end of said rod 24 is connected to one arm of an angle camlever 25, see Fig.

1, which is pivotauy haunted on a stud 26 on a stand 27 secured to theloom side, The other arm of theangle cam lever 25 in this instanceengages the periphery of the cam 28 fast on the bottom shaft 29, and isheld in engagement therewith by a spring 28. The rotation of the cam 28,through the cam lever 25 and rod 24 to the angle lever 22, will at theproper time, positively move outwardly the lever 13, and cause thefilling detector 16, by the engagement of the end 13 of the lever 13with the end 16 of the filling detector 16, to be positively moved awayfrom the shuttle, as shown in Figs. 10, and 12. At the same time, thelever 15, fulcrumed on the lever 13, will be moved outwardly with saidlever 13, until it engages below its ulcrum point with a projection 11on the stand 11, the engagement of the lever 15 below its fulcrum pointwith said projection 11, causes the lower end 15 of said lever 15, to bemoved inwardly, and through the rod 18, the dagger 19 at its engagingend is moved outwardly, Vas shown in Fig. 12, and out of its operativeposition. rThis operation occurs at every other Vpick of the loom, whilethe shuttle is at the opposite end of the loom.

The connector 21 has two collars'21 and 21 adjustable thereon, which areadapted to engage with a bushing 30 which is adjustably threaded into anarm 11 of the stand 11, see Figs. 2 and 4. Said collars 21 and 21 limitthe longitudinal movement of the levers 13 and 15. Y y

A helically coiled expansion spring 31 mounted on the connector 21, andadjustably held at its outer end by two nuts 21 on the connector 21, andengaging at its inner end one arm of thc langle lever 22, acts as agive-way for said lever.

In case the lling 10 on the bobbin 10 is practically or substantiallyexhausted, as shown in F 4, the movement ofthe angle lever 22, throughthe connector 21 and levers 13 and 15, will roclr the filling detector16 and cause it to move into the shuttle box and shuttle, and touch thebobbin, and as there is no movement of the lower end 15 of the lever 15,the dagger 19 connected with said end 15 through the connector 18, willremain in the position shown, and at the forward movement of the lay, asshown in Fig. 1, the end of the dagger 19 will engage the upright arm ofan angle lever 32, see Fig. 5; said lever 32 is provided at its upperend in this instance with a slight offset 32 with which the engaging endof the dagger 19 is adapted to engage to move said lever 32. A veryslight movement of the dagger 19 to the left, Fig. 5', will besufficient to allow said dagger to pass by said lever 32 and leave saidlever at rest.

As long as there is a substantial amount of filling 10 on the bobbin 10the engage- @saisi 'nient ot the tilling detector 16 with the tilling,will hold the tlling'detector a y'ay from the bobbin and Will cause theouter end otI the lilling detector having the ball 1G thereon, to bearagainst and move the upper end lo of the lever 15 toward the inner endot the lay', and likewise cause the lower end 15 ot said lever 15 to bemoved outwardly, and through the connector 18 attached to the dagger 19cause said dagger to be moved to the lett in Fig. Sl, so that theengaging end thereof will not be in position to engage the plate 32 onthe lever but Will pass by said plate 32, and leave said lever at rest,see Figs. S and 9.

rlhe lever has a hub 32" which is looselyv mounted on a stud on a stand3i attached to the loom side, see Vitig. 1. The other arm ot the anglelever 32 has pivotally attached thereto the lower end ot' a verticall)Yextending ivire or rod The upper end ot the rod is guidingl)7 held in anextension 3G on a swinging trame 3G having hubs or bosses 3S thereonloosely mounted on a longitudimtllf.7 sliding rod 37. r1`he longitudinalmovement ot the rod 3T, in connection with the swinging trame 36 iscontrolled in this instance through a lever 3S and a connection 39 to apattern surface, not shown, located at the opposite end ot the loom.This mechanism is t'ully shown and described in a pending application inthe lfatent tiice, Serial lo. 415,62.

A helicall).Y coiled contraction spring l0, attached at one end to thelever 38, and at its other end to a stationary part of the loom, notshown, acts to yieldingly hold the lever 25 and move the rod 3T in onedirection.

The magazine l1 suitably supported, is in this instance ot thestationaryy type and has two vertically extending compartments orguide-Wave 11' therein tvto sets or series ot bobbins 10. t the loiverend of each compartment -11 is located a rocking support or cradle tosupport and release the bobbins 1G, as they maj7 be selected by apattern surface, according to the longitudinal movement of the rod 37and the swinging frame 3e, to bring the upper hooked end ot the uprightrod operated b v the angle lever and the dagger 19, as above described,over an arm 13 or an arm stil, connected With the rocking supports orcradles '-12, to cause the downward movement ot said rod through theengagement ot the dagger 19 ivitli the angle lever 3Q, and through theengagement ot said rod "ith the arm 48, cause the rocking ot the supportor cradle 12 to alloiv the loivest bobbin to drop doivn to be supportedbv said cradle, as shown at the right in Fig. 1.y and at thenenttorvvard movement oi' the lav, in case there is no change ot shuttleboxes at the shifting shuttle box end of the loom, said bobbin 1G willbe dropped to the discharging end of the magazine, and the transterrerarm i5 otl the transterring mechanism, through the engagement ot' thebunter lo on the lay, with the latch il' on the ti'anst'errer arm elo,vvill be operated to transfer a bobbin trom the magazine into theshuttle, as tullj,7 described in said application for a patent, SerialNo. nai-52e.

rihe operation ot the transferring mechanism, through a connector orWire d8 to the lever or arm e?, see Fig. 1, will move down said arm andcause it to engage an arm 50,

fig. 2, on a hub or sleeve 50 on an upright stud 51 at the inner end ofthe shuttle box and rotate said hub7 and cause an arm on the loiver endthereof to be moved inwardly to engage the inner end of the shuttle, seeFig. 5, to position the shuttle in the shuttle box; said shuttlepositioning device is shown and described in a pending appli- C on inthe l'atent dice, Serial No. fl.

rthe movement ot the arm 52 causes it to engage one arm oit an anglelever 53 having the hub .33 pivotally mounted on a stud 54 at the rearof the shuttle box. The other arm ot' the angle lever 53 has adownwardly extending end 53, see lfig. t5, which extends in the path ot'and is adapted to engage a piu on a collar 55 adjustably secured by' iscrew 5e on the connector rod 21, to ct use the movement ot theconnector rod 21 and the lever 1", to the lett Fig. 2, and the c;nsequent movement of the tilting detector lo, to positivel'v7 move-itsfilling engaging end aivav `trom the bobbin 10, and out otl the shuttle,as shown in 5, to allow the removal ot the bobbin troni the shuttle b vthe transferring mechanism.
